Our hosting provider carried out some technical work on the web server that powers the SE1 site this morning.
It looks like the forum database has got a bit mangled in the process, for reasons I can't understand.
A couple of threads that were active this morning are no longer showing up, although the messages are still in the underlying database.
I can't quite figure out how to resolve the issue at present, but please be assured that it's a technical error, not a conspiracy to suppress free speech!
